AI Technical Summary
Technical Problem
Existing mechanical transmissions and modules for vehicle slide-out systems require external drives, leading to bulky mechanisms that occupy significant space and complicate installation.
Method used
The development of self-driven rack guide modules, including skew, intersecting, and parallel modules, which integrate their own drives within a compact module box, enabling high-precision linear motion without external drive sources.
Benefits of technology
These modules facilitate easy installation, maintain high precision under heavy loads, and minimize space occupation, enhancing vehicle interior space and aesthetics while allowing convenient maintenance.

Abstract
This application pertains to three types of rack-and-rail modules with integrated drives and their use in vehicle slide-out systems. The three types of rack-and-rail modules-skew, intersecting, and parallel-each include a module box, worm gear assembly or bevel gear assembly or spur gear assembly, motor, sliders, and a combined load-bearing rack. This application enables high-load and high-precision linear synchronous motion with an integrated drive. The rack-and-rail modules are applied in a vehicle slide-out system that includes, a rack-and-rail skew, intersecting, or parallel module with an integrated drive, a support frame, a load-bearing box, a slide-out. This system facilitates the extension and retraction of the vehicle's slide-out, thereby increasing interior space within the vehicle. The design ensures easy installation and removal while maintaining an aesthetically pleasing appearance.
